Exploring Podman: A More Secure Docker Alternative
Source code for the feature is here if you care to inspect it:
https://github.com/containers/podman-compose/blob/bce40c2db3...
Admittedly, I'm still on podman 4.3.1, but I dont' see any reason why this would stop working in later versions of podman.

Podman Desktop v1.5 with Compose onboarding and enhanced Kubernetes pod data
Can someone link me to what Compose means in this context? Google takes me to https://github.com/containers/podman-compose but I just wanna make sure that's what they are talking about.

Containers Demystified ๐ณ๐ค
๐ Docker Desktop is free for personal use but requires a paid subscription for enterprises. A free open source alternative is Podman and Podman Compose which uses the same core syntax as the Docker tools and can be used as a near drop-in replacement.

Getting Podman running on Ubuntu 22.04 LTS
Iโm dumb. When I wrote the article it was late. Docker-Compose really was a game changer.
Yea Podman compose exists. Iโll add a section about docker compose to it in an update.

Help with updating multiple containers together.
From googling this error I've come across a few different threads but I haven't gained any success. Firstly I found this github thread which doesn't reference my error but still seems related. I followed the "sudo podman-compose systemd --action create-unit" and "podman-compose systemd -a register -f myfile.yml" minus the -f flag as it wouldnt run with that. This indeed created a [email protected] file, but its created in the /etc/systemd/user directory rather than /etc/systemd/system which raises an issue as I'm having to run these two containers as root. I try registering the podman-compose@torrent but I'm told the service doesnt exist. Running it as user I'm told it failed to connect to bus: no medium found. So I basically reached a dead end there.

We're no longer sunsetting the Free Team plan | Docker
Have a look at Podman Compose

SMB Share & Containers SELinux help request.
You can also use podman-compose for the orchestration https://github.com/containers/podman-compose
- We apologize. We did a terrible job announcing the end of Docker Free Teams.
- Docker is now forcing open source organizations to pay. Does this affect Nextcloud?

Colima k8s nix setup
What about the docker-cli? colima also ships with a docker-compatible cli to interact with containerd called nerdctl. We can execute the same docker cli commands like:
- Nerdctl v2 Beta

Nginx Unit โ Universal web app server
Using nerdctl: https://github.com/containerd/nerdctl
I'd really disagree that compose files are somehow one-shot, or blindly modified. To the contrary, really, we have them checked in with the source code. Upon deployment to the cluster, the (running) services will be intelligently updated or replaced (in a rolling manner, causing zero downtime). LXC might be more elegant, but I have no idea what simple, file-based format I could use to let engineers describe the environment their app should run in without compose.
I need something that even junior devs can start up with a single command, that can be placed in the VCS along with the code, and that will not require deep Linux knowledge to get running. Open for suggestions here, really.

Jenkins Agents On Kubernetes
Now since Kubernetes works off of containerd I'll be taking a different approach on handling container builds by using nerdctl and the buildkit that comes bundled with it. I'll do this on the amd64 control plane node since it's beefier than my Raspberry Pi workers for handling builds and build related services. Go ahead and download and unpack the latest nerdctl release as of writing (make sure to check the release page in case there's a new one):

Going through a Kubernetes training with autogenerated captions and about half are coming up like this.
That's why nerdctl, their cli binary, is so well named.

Python + containerd? Who might be interested?
Well, it is indeed a good option. However, containerd is a good alternative that is growing even among developers. Please see: https://github.com/containerd/nerdctl

How to own your own Docker Registry address
Nerdctl/containerd has IPFS support :)

-
DockerHub replacement stratagy and options
nerdctl supports IPFS for both image pulling and pushing, including encrypted images and eStargz lazy pulling. For building, the current method is a locally hosted translator so that the traditional pulls can be converted to work over IPFS. They even have docs on running it on k8s node, though if my reading is correct this isn't exactly a cloud native approach (running systemd services on each node...).
